This is a bill brought by the railroad company, appellee, a
[196 U.S. 599, 605]
Kentucky corporation, against citizens of Kentucky, the members of the state board of valuation and assessment, and, respectively, auditor of public accounts, treasurer, and secretary of state. The only ground of jurisdiction alleged is that, under the tax laws of the state of Kentucky, as administered by its executive officers, the railroad company is deprived of the equal protection of the laws, contrary to the 14th Amendment. The Constitution of the state requires all property not exempted from taxation to be assessed at its fair cash value; but the bill alleges that the county assessors uniformly assess the property assessed by them, which is the great body of tangible property in the state, below its cash value. It alleges that, in like manner, the board of equalization equalizes the county assessments at a percentage not above 80 per cent of the fair cash value of the property taxed. On the other hand the defendants, who assess the franchise tax on the railroad company, are alleged to have assessed the company's property in Kentucky at its full value, viz., $33,788,724.50, for the year 1902, and then, deducting the tangible property locally taxed, $23,103,825, to have made the taxable franchise $10,774,899.50. Whereas, if 80 per cent of the value of the company's property had been taken, then, deducting as before, the taxable franchise would be only a little over $4,000,000.

The railroad company contends that when there is a uniform and general undervaluation of other property, then the only way in which the company can be put on an equality with other taxpayers is by a similar undervaluation in its case. The railroad company contends further that although this contravenes the letter of the statute, the requirement of equality so far outweighs the requirement of a tax on the full value of property, that if, by misconduct elsewhere, both cannot be observed, the rule of equality must prevail. It should be mentioned that the franchise tax is both state and local, and that after the same has been laid and apportioned between the state and county, etc., by the defendants, the
[196 U.S. 599, 606]
state auditor, who is one of them, certifies to the county clerks their proportion of the tax. The bill prays for an injunction against such an apportionment and certification, and also against collection by the officers of the state. There was a general demurrer to the bill, and an answer and replication. The demurrer was overruled. Much evidence was taken, and at the final hearing a decree was entered by the circuit court enjoining the defendants as prayed, and requiring the defendant Hager, treasurer of the state, to execute a receipt in full of the state taxes on the franchise for 1902, the plaintiff having paid the sum which was due on its view of the case. 131 Fed. 282. The defendants appealed to this court. It may be assumed from an affidavit filed, if not from the pleadings that the amount in controversy is over $2,000. See United States v. Trans- Missouri Freight Asso.

From a consideration of different kinds of evidence the circuit court reached the conclusion that the county assessors had systematically and intentionally undervalued the property assessed by them. In the first place it found a settled habit of undervaluing, recognized by the legislature and the state court, before the adoption of the Constitution of 1891, which required the fair cash value to be assessed. It found that while the value of land had increased or, at least, had not diminished since 1891, the assessments had varied very little, while those of 1891 were not more than 70 per cent of the value at any time. It considered testimony that from 1893 to 1896 the assessments were equalized at 70 per cent, following earlier statutes, notwithstanding the Constitution of 1891. It then compared tabulated statements of sales in the different counties, which were required by statute to be furnished to the board of equalization, with the local assessments and with the results reached by the last-named board. It thus found an additional and independent reason for believing that there was systematic undervaluation in the counties, and it inferred from comparisons and from testimony to that effect
[196 U.S. 599, 607]
that the board paid little attention to the tabulated statements, even on a basis of 80 per cent, but really was governed by the assessment of the previous year. Finally, it confirmed its conclusions by direct testimony as to the practice in certain counties and the rules practically adopted by the board. The reasoning is careful and elaborate, and cannot be read without an impression that probably it is correct to the extent of establishing a general undervaluation of land.

On the other hand, there was testimony that the statements of sales did not afford satisfactory evidence of average values, or at least, for various reasons, were not regarded by the board of equalization as affording it. Most of the members of the board testified that they tried in good faith to reach fair cash values, and there were many affidavits to a like effect as to the past and present conduct of the county assessors. It was sworn that, so far as percentages of the reported sales were used, they were used on an estimate of what proportion actual values would bear to the sums named in the deeds. The circuit court, while regarding it as the condition of equitable relief that the property other than that of the plaintiff should have been undervalued systematically and intentionally, hardly dealt with this evidence in its bearing on the question of intent. Yet, of course, no court would venture to intervene merely on the ground of a mistake of judgment on the aprt of the officer to whom the duty of assessment was intrusted by the law.

The other half of the plaintiff's case is that its franchise was valued at its full cash value. It might even require consideration, if necessary, whether it ought not to be shown further that the appellants, in valuing the franchise, consciously adopted a different standard from that which they understood to be adopted in the counties. On the foregoing questions one of the three appellants testified that he had dissented from the majority on several occasions, believing that the assessments were higher than those for other kinds of property, and that he understood that the majority assessed
[196 U.S. 599, 608]
the franchise at its full value. One testified that he thought at the time, and still thought, that the franchise was valued lower than it ought to be. The third was not explicit, but showed that the valuation was reduced after hearing. Different wellknown modes were used in approaching the valuation, but probably there was an element of arbitrary judgment at the end. This certainly was the case in regard to the proportion of mileage in the state, which, by the statutes, was to 'be considered' in fixing the value of the franchise, and which the appellants contend was underestimated so much as to compensate for any other mistake, if there was any, which is denied.

We need not stop to show that so much of the bill as seeks an injunction against collecting the state tax, and the portion of the decree which orders a receipt to be executed on the part of the state, cannot be maintained. See Coulter v. Weir, 62 C. C. A. 429, 127 Fed. 897, 906, 912. On the other hand, in a proper case, a bill may be brought to restrain apportionment and certification to the counties. Fargo v. Hart,
193
U.S. 490, 495
, 503 S., 48 L. ed. 761, 764, 767, 24 Sup. Ct. Rep. 498. The question is whether such a case has been made out, and we may assume, for purposes of decision, without deciding, that, if we otherwise agreed with the railroad company's contention, the injunction might be granted, although the franchise was valued as the law requires in every respect except in the proportion which the assessment bore to the other valuations. The decisions are not agreed upon this point.

We have stated as much as we deem necessary to the answering of the question just put. It must be obvious on even that short statement how uncertain are the elements of the evidence, and in what unusual paths it moves. On the face of their records the proceedings of the defendants, of the county assessors, and of the equalizing board all are regular. If it be a fact that the franchise of a Kentucky corporation is taxed at a different rate from the tangible property in the state, there can be no question that the state had power to tax it at a different rate, so far as the Constitution of the United States
[196 U.S. 599, 609]
is concerned. Bell's Gap R. Co. v. Pennsylvania,

191 U.S. 165
, 48 L. ed. 133, 63 L. R. A. 571, 24 Sup. Ct. Rep. 53. But as the claim of right under the United States Constitution was not merely colorable (Penn. Mut. L. Ins. Co. v. Austin,
168
U.S. 685, 695
, 42 S. L. ed. 626, 630, 18 Sup. Ct. Rep. 223), and as the evidence is here, we have considered the evidence also, and our conclusion from that, as well as from the law, is that the bill must be dismissed.

Looking first at the assessment of the franchise, there is no such certainty that it was made on a different scale of values from that adopted elsewhere as would warrant an attack upon it under the 14th Amendment, even if otherwise that attack could be maintained. But the supposed infringement of the 14th Amendment is the only ground on which the railroad company could come into the circuit court, and if that ground fails, and obviously fails, the court should be very cautious, at least, in interfering with the state's administration of its taxes upon other considerations which would not have given it jurisdiction.

The undervaluation in the counties, looked at from the point of view just indicated, also does not appear to have been such as to warrant the action of the court. It is not contended that a mere undervaluation would be enough. It is admitted that it must have been systematic and intentional. There is, no doubt, a natural inclination to think such an undervaluation probable when it is suggested. But what is the proof? The state Constitution, whatever the statutes may have said, seems popularly to have been understood to have made a great change in the law. Practice before its adoption, therefore, hardly can raise a presumption as to practice afterwards, even on the liberal assumption that it properly could be considered in evidence. It is obvious that the accidental sales in a given year may be a misleading guide to average values,
[196 U.S. 599, 610]
apart from the testimony that some, at least, of the conveyances did not report true prices, yet they furnish the chief weapon of attack. The testimony as to the board of equalization taking 80 per cent of the reported sales was explained by the members of the board. It would be going very far to assume that they were committing perjury because, to another mind, the sales seemed more significant and the explanations not very good. Inequality, we repeat, is nothing, unless it was in pursuance of a scheme. To make out that scheme the anomalous course was followed of putting members of a tribunal established by law upon the witness stand to testify to the operations of their minds in doing the work intrusted to them. Fayerweather v. Ritch,
195
U.S. 276, 306
, 307 S., ante, p. 58, 25 Sup. Ct. Rep. 58. But the prevailing testimony was that no such scheme was entertained.

Whatever we may surmise or apprehend, making allowance for a certain vagueness of ideas to be expected in the lay mind, for the reasonable differences of opinion among the most instructed and competent men, and for the uncertainty of the elements from which a judgment was to be formed in the first instance, considering the still greater uncertainty of those from which the local judgment must be controlled, if at all, by persons having only the printed record before them, considering further that to maintain the bill imputes perjury to many witnesses whose character is not impeached, and, finally, recalling once more that we are dealing with a case that properly was not cognizable in the circuit court, we are of opinion that the bill must be dismissed.
